To all 'who/m, t may conce/m: n v

Be it known that 1, CHARLES B; BUSH', a Citizen of the United States,4residingA at Kiefer, in*l the county oftGreelry and` State of; Oklahoma,have invented certain new and useful improvements in; an Oil-NellBarrel, of Wi'iieh the following is a speeiii-r cation.

This invention relatesto; deep oil Wells and Water pumps: a d thepriere-ry' ebi'et et this: invention is to) provide an linproved meansfor taking; cere et fleeting s deep; wells7A so` that, the i Y eectivelyunder these- 20.; tiene a l prevent the doggie? unof? the Working andstanding valves. i

Ano-ther pri-:ne objectot the ni-Vention is to provide a norelsandtr-ap.. for oil Well pninps embodying meanstor permitting the oil;to taire a tortuons, course through the uell easing or liner', so4 thatsand earriedj thereby will; be deposited in thesand trap.. providedA forthe saine. Y

Another prime object. of' the inmentioir is to. provide means forpermitting a second etleiding rvalve tovv be quickly and readily droppedinto anr operative-I position when the first standing` Valve becomesleali-y or otherwisel inoperative. p

Another objeot et the invention is. to provide a novel Workiiuqr valveand barrel arrangement', whereby any sand', r theV like that may havebeeny Carried past the. rst sand trap willl be. deposited in a' secondsand trap, thereby insuring the eleetixre delivering of the oilin asubstantially @lean condi- Y tion.

A still further object of the; invention is to provide aniniprovedfdev-ice ot theabore charact-er7 whichv will be. thnable-A and edi;-eient in` use,V one. that will be siinp-l'e and easy, to manufacture andone which can .be placed upon the market and incorporated vwith. a deepoil Well at a niiniinum; cost.r

lilith these and other objects in- View, the

invention. consists.A in thenovel eonstruetion,

Referring to the drawing in detail;7 Wherein similar referencecharacters designate. corh respondingy parts. throughout; the severalvisive', the letter A generally indica-tes the improved deep; Wellypump, whichy embodies the outer casing or liner The. casing or liner B;consists of the Workingvalve portion 101,- the secondary standing valveportion 11 and the lower primary standing value. and trap portion; l2;The upper portion or section i. of the casing; or lining B has:conneeted thereto a cast-ing 13', Whilethe sections 10 and 11 areoonneetedby the Workingtalve casting14.l and theseotions il l2arefoonnected by the drop. Valve Cast:- ing or secondary standing Valvecastingy The lower end of the sect-ion 12' has conneoted thereto a lowercasting 16'. Disposed within the upper Working Valve section4 orpertionlO; isa workingbarrel which is held axially within the portion10l by ineens ott-heworking Valve casting 14 and itcan be. seen that theworking barrel is tl'ireaded into engagement therewith.- A bell collar21 is` threaded on the upper end of the Working;v barrel 20. and carriessuitable guide or spacing` lugs 22 for holding the upper end of the'barrel inv proper spaced relation to the liner` or- Casin-g B'. It is tobe noted that thebarreli ZO'i-s-arranged in spaced relation tothe'seetion 1'0 of the liner A' which :torins a sand and sediment trap`23. Reciprooab-ly mountedY Within the woijleingbarrel 20y is the Workingrplunger 25, andit; is toi be noted that this plunger is of a relativelygreat length so as; to extend substantially the! full length off theWorking barreland that when the upper end thereof slides out of theworking barrel, the loiver end thereof Will come into the loiver end ofthe Working barrel. As clearly shown in Figures l and 1A, thel workingbarrel embodies tubes or sections 26 and 27 which are connected togetherby means of a sleeve 28 that carries a plurality of packing gaskets orcups held in place by suitable retaining rings 30. These gaskets or cups29 are adapted to frictionally enthe inner surface of the barrel 2O inorder to prevent the leakage of the fluid from around the saine. rTheextreme lower end oli the section 27 of the Working plunger is attachedby suitable means a cup or gasket 31 for frictionally engaging the innersurface of the barrel. The upper en d of the Working plunger 25 alsocarries a suitable gasket or cup 32 for 'trictionally engaging` theinner surface of the Working barrel and the sleeve upon which the cup ismountet supports the ivor Vring or operating valve 34. This Valve 34embodies a valve seat connected directly with the sleeve 33 and avalvecage 36. i4. ball valve 37 is employed for fitting upon the seat 35.

Extending axially up into the liner A is t-he fluid pipe 40 and thispipe is held in place by the lower casting 16 and it is noted that thefluid pipe is spaced from the section 12 of the liner A which forms asand trap 41. The extreme upper end of the fluid pipe 40 supports thestanding valve 42 which will be hereinafter lnoivn as the primarystanding valve. As shown this standing valve 42 embodies the annularvalve seat 43 upon which is adapted te lit the ball valve The ball valveis held in place by means of a suitable valve cage 45. The upper end ofthis valve cage 45 carries a supporting lug` 46 upon which is mountedthe filter tube 47. The filter tube 47 is arranged in spaced relationbet/Ween the fluid inlet pipe 40 and the section l2 of the liner A andhas its upper end provided with a head or Wall 48, the axial center' ofwhich receives the support-ing lug 46. rhe filter tube 47 can beprovided with a plurality of openings 49. It is to be also noted at thispoint that the filter tube 4T terminates short of the loiver end of thesection l2 ot the liner A. Spad ing lugs 50 are carried by the lower endof the filter tube so as to maintain the lower end thereof in correctposition to the inlet fluid tube 40.

lrrranged between the primary standing valve 42 and the Working valve 34is the dropping or secondary standing valve This valve is only broughtinto use when the primary standing valve ecomes leal-:y or otherwiseinoperative. Permanently arranged Within the secondary standing valvesection ll of the liner il is a supporting pipe .5G which is threadedinto the dropping or secondary standing valve casting 15 and thissupporting pipe carries a sleeve 57 having its upper end flared as at 5Sto form a guide for the secondary standing valve when the saine isdropped into place. rlhis Yflared guiding portion can be provided withsuitable outlet openings 59 il? so desired. The dropping or secondarystanding valve embodies a valve seat (SO upon which adapted to normallylit the ball valve (Sl and this valve is retained into position by meansondary or dropping standing valve at largest point is of a lessdiameter' than the Working valve 25 so as to permit the same to bedropped into position through the said barrel when the primary standingvalve be comes inoperative.

ln operation of the improved device it can be seen that 'the Workingvalve and plunger is reciprocated in the ordinary manner through thepump rods (not shown). Un the upstroke of the plunger the valve 37 Willof course be held on its seat and the fluid Will be drawn up by suctionthrough the fluid inlet pipe 4l) and unseat the valve ot the standing`valve structure 42 and will flou' down bet-Ween the fluid pipe 40 andthe lilter tube 47. The fluid Will then flow through the openings 49 andthrough the lower end of the said filter tube. After which the fluidWill be sucked up between the lilter tube 4T and the section l2 of theliner A up through the plunger. lt is new apparent that as the fluidflows through the opening of the filter tube and begins its unwardpassage that any sand or sediment carried therewith Will be permitted todrop dor-In into the trap 4l and thus the oil or other vfluid isrelieved of all sediment. New on the down-stroke of the Working valveand plunger the valve of the standing valve structure 42 will be heldclosed while the valve 87 of the Working valve Will be unseated Whichwill permit the fluid to floiv up through said valve and out of thecasting lZ-l into the oil vell pipes. its the lluid flows out of theWorking valve any sediment7 sand or the like that still may be retainedtherein will be permitted to drop back into the trap 2S provided forthat purpose.

New When the primary standing valve becomes inoperative, it is merelynecessary to lift or ufithdraiv the plunger from position and drop thedroppingor standing` valve 55 in place, after which the saine wilfuni-,tion as the ordinary standing valve.

From the foregoing description it can be 'face elf the sleeve lb lll)seen that l have provided an exceptionally simple and durable means forhandling oils containing floating sands and the like.

Changes in details may be made Without departing,` from the spirit orlie scope of this invention.
